The sales price of a single family house in Charlotte is normally distributed with mean $210,000 and standard deviation $35,000.

Lady_Fox [76]

Answer:

E(X ¯)=210,000.

Step-by-step explanation:

A sampling distribution for samples of size n=49 from a population with means μ=210,000 and standard deviation σ=35,000, has the following means anda standard deviation:

$\mu_s=\mu=210,000\\\\\sigma_s=\sigma/\sqrt{n}=35,000/\sqrt{49}=35,000/7=5,000$

If X ¯ is the mean sales price of the sample, it will have a mean value of E(X ¯)=210,000.
